Funcionamento das messes da Polícia de Segurança Pública: vantagens e desvantagens na utilização de pessoal com funções policiais

A escassez de recursos obriga, por parte das organizações, a adoção de novos mecanismos que permitam uma gestão racional dos mesmos, visando obter o máximo de eficácia e eficiência. Os recursos humanos nas áreas de apoio social são, e em concreto na confeção e distribuição de refeições, cada vez mais, uma preocupação da Polícia de Segurança Pública, que sendo constantemente confrontada com carências, tem procurado responder com soluções pontuais de forma a garantir o funcionamento dos serviços. O eventual recurso a contratação de serviços externos, pela Polícia de Segurança Pública, para as messes, assume, nos dias de hoje, crucial importância, na gestão dos recursos humanos, sendo possível, utilizando este mecanismo, eventualmente redirecionar pessoal policial para outros serviços, e ainda proporcionar uma melhoria nos serviços de apoio.The scarcity of resources requires, from the organizations, the adoption of new mechanisms that provide a rational management of the resources, in order to achieve maximum effectiveness and efficiency. Human resources in the areas of social support, and in particular on cooking and distribution of meals, are more and more, a concern of the Polícia de Segurança Pública, which is constantly being faced with shortages, has sought to respond with specific solutions in order to ensure the functioning of the services. The possible use of external services into the messes, by Polícia de Segurança Pública, assumes today, crucial importance, in the management of human resources, and it is possible, using this mechanism, eventually redirect police personnel to other services, and still provide an improvement in support services.N/

European contribution to the study of ROS: A summary of the findings and prospects for the future from the COST action BM1203 (EU-ROS).

The European Cooperation in Science and Technology (COST) provides an ideal framework to establish multi-disciplinary research networks. COST Action BM1203 (EU-ROS) represents a consortium of researchers from different disciplines who are dedicated to providing new insights and tools for better understanding redox biology and medicine and, in the long run, to finding new therapeutic strategies to target dysregulated redox processes in various diseases. This report highlights the major achievements of EU-ROS as well as research updates and new perspectives arising from its members. The EU-ROS consortium comprised more than 140 active members who worked together for four years on the topics briefly described below. The formation of reactive oxygen and nitrogen species (RONS) is an established hallmark of our aerobic environment and metabolism but RONS also act as messengers via redox regulation of essential cellular processes. The fact that many diseases have been found to be associated with oxidative stress established the theory of oxidative stress as a trigger of diseases that can be corrected by antioxidant therapy. However, while experimental studies support this thesis, clinical studies still generate controversial results, due to complex pathophysiology of oxidative stress in humans. For future improvement of antioxidant therapy and better understanding of redox-associated disease progression detailed knowledge on the sources and targets of RONS formation and discrimination of their detrimental or beneficial roles is required. In order to advance this important area of biology and medicine, highly synergistic approaches combining a variety of diverse and contrasting disciplines are needed.The EU-ROS consortium (COST Action BM1203) was supported by the European Cooperation in Science and Technology (COST).

Arginine supplementation modulates pig plasma lipids, but not hepatic fatty acids, depending on dietary protein level with or without leucine

Abstract Background In the present study, the effect of arginine and leucine supplementation, and dietary protein level, were investigated in commercial crossbred pigs to clarify their individual or combined impact on plasma metabolites, hepatic fatty acid composition and mRNA levels of lipid sensitive factors. The experiment was conducted on fifty-four entire male pigs (Duroc × Pietrain × Large White × Landrace crossbred) from 59 to 92 kg of live weight. Each pig was randomly assigned to one of six experimental treatments (n = 9). The treatments followed a 2 × 3 factorial arrangement, providing two levels of arginine supplementation (0 vs. 1%) and three levels of basal diet (normal protein diet, NPD; reduced protein diet, RPD; reduced protein diet with 2% of leucine, RPDL). Results Significant interactions between arginine supplementation and protein level were observed across plasma lipids. While dietary arginine increased total lipids, total cholesterol, HDL-cholesterol, LDL-cholesterol, VLDL-cholesterol and triacylglycerols in NPD, the inverse effect was observed in RPD. Overall, dietary treatments had a minor impact on hepatic fatty acid composition. RPD increased 18:1c9 fatty acid while the combination of leucine and RPD reduced 18:0 fatty acid. Arginine supplementation increased the gene expression of FABP1, which contributes for triacylglycerols synthesis without affecting hepatic fatty acids content. RPD, with or without leucine addition, upregulated the lipogenic gene CEBPA but downregulated the fat oxidation gene LPIN1. Conclusions Arginine supplementation was responsible for a modulated effect on plasma lipids, which is dependent on dietary protein level. It consistently increased lipaemia in NPD, while reducing the correspondent metabolites in RPD. In contrast, arginine had no major impact, neither on hepatic fatty acids content nor on fatty acid composition. Likewise, leucine supplementation of RPD, regardless the presence of arginine, promoted no changes on total fatty acids in the liver. Ultimately, arginine, leucine and dietary protein reduction seem to be unrelated with fatty liver development
